Abstract
A detection and localization system mounted on an airborne vehicle, and which enables detection of objects having at least one face inclined relative to the surrounding flat horizontal ground and therefore presenting a contrast with this ground. A radar transceiver is connected to an antenna rotating around the airborne vehicle and has a low directivity in a pitch plane and a high directivity in a roll plane, associated with a generator of distance cells. Making use of mathematical relations, an on-board computer, knowing the altitude of the airborne vehicle and the roll angle of the emitted radar wave, localizes the inclined face which produces a much higher reflection of the emitted radar wave than the surrounding ground, to thereby detect the inclined face.
